为什么WLS中的JMS消息桥每30秒停止/启动一次

我遇到了一个问题，我的JMS消息桥似乎每30秒被WLS停止并重新启动一次

据我所知，网桥实际上工作正常，WLS控制台将其报告为“活动的转发消息”。据我所知，桥两端的两个队列都工作正常

我的WLS日志中每30秒显示的消息如下所示。这六行每次都重复

（需要Oracle帐户），这是异步JMS桥的正常行为

文档中的问题描述为：

使用WebLogic Server 9.2及更高版本；在配置了JMS并设置了JMS消息传递网桥的域中，JMS消息网桥的日志记录显示每30秒断开并重新连接到源目标

从Oracle的角度来看，这是正常的预期行为：

这是一种轮询机制，通常发生在源-目标中没有消息时，以及消息桥处于空闲状态时

---

由于异步网桥会出现这种情况，因此阻止这种情况发生的方法是禁用JMS消息传递网桥的“异步模式启用”选项，这将停止它的轮询。

您能从配置中发布定义的

消息传递网桥吗？我的原始答案已被主持人删除，因此，我无法请求在编辑后将其取消删除。为了更好地回答这个问题，我重写了我的答案。
